To all whom imay/ conce/rn: Be it known that I, ETHAN I. Doubs, a

` -I citizen of the United States, residing at Central Valley, Orange. county, New York, have invented a new andv useful Improvement in Electric Fans tor .Railway-Cars, of which the following is a full', clear, and eX- act description, referencebeingl had to tli'e accompanying. drawings, forming part of this specification, in wliich Figure lis a vertical sectional View illus-Y trating one forinofiny invention, and showing the concealed position of the fan in full lines, and its working position in dotted lines ;`1I*` ig. 2 is a top planV view with a portion of the casing removed; Fig. l3 is a sec- -tioii on the liney IIL-Ill of Fig. 2;- Fig. 4: is a' front elevation or' thev cover plate; Fig. 5 is a wiring diagram ofthe motor circuits; Figs. 5 and l'fare respectively plan and side views with` portions insection. showing a modiiied mounting of the fan; vand Fig. 8 is a vertical sectional view showing another modication.

.l My invention has relation to electric :tens

whichore particularly designed for use on railway trains. l

The object of 'my invention is -to provide an kelectric fan and arrangement thereof adapted for use in the berths, sections, or

. state rooms of a railway car, the fan being placed in a pocket in the walls offthe oar, In one form of my invention I providemeans whereby the fan can be .swung outwardly from thepocket when in operation somewhat in the manner ofan' ordinary electric berth lamp. I also preferably provide means whereby the direction vof rotation of the fan may be reversed so that it may be operated either tosupply freshair to the 'berth or section, .or to exhaust the air there-I imm My Vinventionis susceptible of various `arrangements in detail. In the accompanying drawings, I have. shown a number of differ- 'ent4 arrangements, which will' nowv be dcscribed, referencebeing first h ad to that form of my invention .shown in FigsI 1 to 5, inclusive. In these figures, the numeral 2 designates 'a portion A of theV sidefiwall casing of a railway car, and'in which 1s formed a.

pocket B for the reception of the electric fan.' The pocket .3 :hay have a Ventilating connection with the outer airv 1n any suitable .mannen Seated in this pocket is a fixed 'inent for the motor.

casing 4, within which is supportedthe fan 4 3 and its electric driving motor 6. The motor' is supported from a hinged front plante?v arranged to be swung outwardly and upwardly on theH axis 8. This plate has the inwardly projecting arm 9 terminating in'a ball end 10, which has a swivel bearing in the socket 11 at the center of the motor', being secured therein by the keeper ring 12 and mit 13. I have .shown the ball head 10 as formed in two sect-ionswvhich are kept expandedfinto a close bearingfit in the walls of the socket .by means' of aninclosed spring le. The armature shaft of the motor has .the extension i l5, to which the fan 5 is secured. 16 is a.

su-itable'screen guard secured to the casing l-i' of 'the motor. Owing to the hall and socket connection between the motor and the erin 9, the fan and motor are capable oa universalswiveling movement to give any desired angular position of the. fan. permit this, the arin '9 is. slotted, as'indicated at' 18, to engage the yoke portion 19 oi the motor casing. The rear por ion of the :fixed casing 4; is shown as provided with a plurality of openings 2,0. The motor and fan are normally secured within the pocket Bby means of any suitable latch, such as that shown at 2l, engaging thelower part of the hinged plate 7, and controlied by a suitable push A'bntton projecting throughV the lower frontv part of the lcasing 4i.' The fan and motor may be held in the exposed position shown inl dottedlines in Fig. L1, by ineens of thegspringpressed detent 23, which ijs adapted to snap into the recess 24 in the pivotal portion of the plate Y in'such a manner as to hold the parts int-heir open'` position. pulled downwardly by the hand, the pres- When, however, the plate 7 is sure ofthe spring 25 which controls 1 the 'latch 23 may be overcome. The 'front plate 7 is preferably provided with a series of openings 26, for the purpose hereinafter de scribed.'

"In Fig. 5 .l2-have shown a wiring diagram, which illustrates a suitable circuit arrange- In this diagram 2.7 designates the source of current supply, which may be thesource which supplies the ,lighting system of' the car or train. 28' designates the field winding of the rnotor, and 29 its) armature. 30, 31 .and 3Q designate threerelatively fixed switch contacts, whichy are cornice-ted in* multiple to one side of lil() supply line, and 33, 34 and 35' designate three other contacts which are connected in multiple to the other side of such line. 37, 3S and 39 designate three contacts which are connected in multiple to one side of the motor circuit, and 40, il and Lil-2, three other contacts which are connected in multiple to the other side of the motor circuit. circuits betwee'ri the respective pairs of contacts SO and 40, 35 and 39, 33 and 4Q, and 32 and Si', are controlled'by the two movable switch devices 43,1 and 4 4. vEach of these switch devices consists of a rotary plug having a conducting segment and a non-conducting segment, the end et the plug projecting outwardly throughcthe upper` portion of the casing Lt and being provided with a button 45, or other suitable actuating device. @ne set of the contacts 3l and 34|-, 38 and 4l, as for instance, the contacts 38 and 4l, are carried by the movable front plate 7; and when said tt'ront plate is swung upwardly on its pivot 8 in the position shown in dotted lines in Fig. l, these contacts are caused to engage the contacts 3l and 34, and thus close the motor circuit. ln Vthis manner, the mere act of raising the motor and tan to the position shown in dot ted lines in Fig. l., establishes the circuit ot the motor and starts they, tan into operation. lt is desirable, however, to provide means ,whereby the tan may be operated in either direction while inclosed in tbepocket 3; and it is for this purpose that the 'switch devices 43 and 44 and other coperating contacts are provided. `l`he operation of one ot these switch devices will cause the fan to be driven in a direction to exhaust air from the berth, whileby means oi the other switch device the fan may he driven in the opposite direction to supply 'fresh air tothe berth. Thisl circulation of? theY airis made possible by reason of the openings 2O and 2G in 'the casing'.

In the modification shown in Figs. 6 and 7, the motor casing 4G is shown as swiveled on trunnions 4T, ,which are carried by the arms of a yoke /i-S. 'This yoke is inturn carried by a stub sha lit 4:9. which is provided, at the outer side oi the front casing member 7 with an actuating button 50 by means of which it can lic turned to vary the angle of 'the` ian. rthe vtan may also -be turned about the aXis ot the trunnions 4l-7, and tor the purpose ot securing the fan in the desired adjustment with respect to this axis, the trunnions may taire .the torni of set screws. as shown.

in the modification shown in Fig. 8, the vmot-omis supported in substantially the same mannet as shown iii-Figs. (i and Y, but the yoke l which carries thc truunions- 52 is sccurcrfl to the bottom wall-,53 oi the wall pocket 3. In this 'form of my invention the The tilation of that particular berth or section, t

as may be desired. The provision of means whereby the fan may be operated, either as an exhaust fan or as an air supply fainwhile within the wall pocket, is also a feature of great advantage, since it enables the provision of a good air supply within the berth or section without subjecting the occupant to the direct action of the fan.

lVliile, as above stated, the invention is especially adapted for use on railway trains, it isobvious that it can be used upon boats vand in houses or other buildings. It will also be apparent that the details of construction and arrangement of the parts may be widely varied without departing from the spirit and scope ofmy invention as defined in the appended claims.
